Grapple up into the rafters of the warehouse and look for the nearby Collectible sitting on some boxes.

As you head out, you'll be greeted by a Polycraft. Swing around the nearby pipes to get a grip on it and Zip Kick it into oblivion. Alternately, if you have any SJMG ammo remaining you can use it to drain some of the Polycraft's health bar. Now, head out over the many pipes along the side of the level. You'll see a pod drop ahead.

Collectible 2

Just above it is a Sniper, so toss him out of the way, then use the YELENA from the pod to hit the Sniper on the pipe across the way. If you have mad bionic skills, you can use one Sniper to nail the other with a deft toss! Don't forget to swing out to the Collectible in the air by the pod before you move on.

Collectible 3

Grab your SJMG back and swing over to the bridge with myriad grunts on it. Above the tower marked "2" is a Collectible. You can grab some ammo up here as well. Use a DFA or Whip Spin to make short work of the grunts. At the shield gate, two standard Biomechs appear. Use DFAs to stun them then Zip Kick or Grenade them until they're scrap metal.

Inside the warehouse lie about a dozen Grunts and Heavy Grunts The high ceiling of this warehouse makes this a good spot to get your Shellshock Challenge. The key to doing this is to hold back and weaken as many Heavy Grunts as you can from a point just up from the entrance on the ground.

Here you can take cover behind pipes and take potshots with the YELENA or SJMG. Weaken the Heavies and try not to kill the others. As they swarm in the corner near the ramp or near a cargo container, zip above them and perform a Death from Above. If you catch five (weakened) Grunts in the ring of the DFA, the Challenge is yours! Thankfully, just ahead is a RELAY you can hack for a save point. Phew!

Collectible 4

Using the deactivated mines, swing towards the pod that drops on a cylinder far in the distance. Grab the Bulldog, and swing to the Collectible out over the water. Be sure to eliminate the nearby Grunts first.
